IMPROVEMENT IN GRAIN-BINDERS.

Specification forming part of Letters Patent No. 222,829, dated December23, 1879; application filed March 3, 1879.

To all whom t may concern:

Be it known that I, SYLvANUs D. LoeKE, of Hoosiclr Falls, in the countyof Rensselaer, in the State of New York, have invented new and usefulImprovements in Automatic Binding-Machines and Harvesters, of which thefollowing is a full and exact description.

This improvement relates to the twisting, holding, and cutting devicesthat sever and hold the ends of the wire and secure them to getheraround the bundle, and for convenience they will be described inconnection with the band-carrying and other mechanism of an au tomaticbinder which form the subject-matter of separate Letters Patent, and forwhich I make no claim in this patent.

The object of my present improvement is, primarily, to secureintermittent rotary movement of both twister and cutter and holder inthe same direction, but with different intervals of rotation and rest,and to perform these various and intermittent operations in the simplestand most economical mannerto wit, by the employmentof parts that areduplicated by casting and need'no fitting as to their working parts; andmy invention consists, first, in the peculiar and novel construction andoperation of a wheel, pinion, and a twister having opposing and radialleaves or hooks, whereby the continuous movement of the wheel duringrevolution shall, by means of gear-teeth and stop-plates alternatelydisposed on the Wheel and also on the pinion, and preferably castthereon, give to the twister first a halfrevolution, then an interval ofrest, and then several revolutions, followed by a second interval ofrest, during each full operation of the binding machine, therebyenabling the twister itself to dispose the two ends of the band on theopposite sides of its axis, and then to twist them together, after whichit is withdrawn and securely held out of the field of entanglement withthe grain or band .material during the time they are being presented andadj usted in the machine and until again called to perform its functionof securing the ends of the band.

My invention also consists in a similar novel and peculiar constructionand operation of a twister, band holder and cutter, and theiroperating-pinions, with a single and preferably a cast wheel, wherebythe various and complicated and intermittent movements and stops of thetwister, holder, and cutter are secured by the simple rotation of thewheel, as hereinafter set forth.

My invention also consists in the employment of a looper-preferably asimple piece of l bent wire-underneath the twister, whereby thc ends ofthe band may be loosened and severed before the operation of twistingthem together has proceeded far.

My invention further consists in other details of construction andoperation, as herein set forth and described.

That others may fully understand the construction and operation of myimprovements, I will particularly describe them, having reference to theaccompanying drawings, where- Figure 1 is a transverse section throughthe binding apparatus, showing the gatheringarms, binding-arm,wire-spool, and twisting mechanism in position. nal sectional elevationof the driving-shaft, representing the twisting mechanism and itsdriving-gear in position. Fig. 3 is a perspective view of the twistingdevices detached. Fig. 4 is a transverse section, same plane as in Fig.1, but enlarged, and showing the twisting mechanism in operation. Fig. 5is a longitudinal section of the twisting device. Fig. 6 is an elevationof the same. Fig. 7 is a plan view of the same.

J is the principal shaft, which receives its movement from the primemover in any suitable way, as by means of a belt or chain passing overthe wheel K mounted loosely upon said shaft, and provided with a clutch,L, whereby said wheelV may be locked fast to said shaft, or unlockedtherefrom at pleasure..

The binding-head Q, as herein shown, receives its movement from saidshaft J, and the gavel, taken from the receptacle of the binder, iscarried against the wire,`"partly looping the latter around it by meansof the arms M.

The binding-wire is wound upon a spool, d, suitably located upon themachine, and from thence passes to the roller at the end of thebinding-arm, and its end is griped by the wireholder.

When the gavel has been raised against the Fig. 2 is a longitudi.

wire by one of the arms M the binding-arm descends, carrying the wirearound the gavel and bringing th'e ends of the band together andpresenting them to the twister and cutter, whereby' they are twistedtogether and severed, and the new end again griped, when the binding-armrecedes and the bundle is discharged.

Upon the shaft J there is mounted and attached thereto a wheel or gear,A, of peculiar construction, whereby theA twister and cutter areintermittently caused to operate.

The twister D and cutter E, with their driving-pinions F G, aresupported and take bearing in the bracket B, that is bolted to the frameof the machine. The bearing C of this bracket has its axis preferablyradial as to the axis of the wheel A.

rIhecutter E is hook-shaped, and extends radially from its hollow shaftor axis. Its upper and under surfaces are hat, and its front upper edgeis shaped so as to form a cutter, while the under surface has its frontedge rounded and arranged to join the wire between it and theabutment-plate e of the bracket. The shaft of said cutter is tubular orhollow, and extends through the bearing C, and has at its other andlower end a pinion, G, attached thereto. The twister is formed by twohook-shaped arms extending at right angles and in opposite directionsfrom its shaft, which is inserted through and takes bearin g in thetubular shaft of the cutter E, and is terminated at its other end by thepinion F.

A looping-piece, H, preferably a piece of wire, is secured to thebracket B in any suitable manner, as by a set-screw cr belt, h, and itsfree end extends toward the shaft of the twister, and is curved nearlyaround the neck of the twister, and at a short distance therefrom, justbelow the twisting-hooks and between them and the cutter E. After thetwister has made a half-revolution or more the ends are severed orloosened, and the object of the part EI is to prevent these ends fromescaping from the twisting-hooks while the latter are twisting themtogether. This object is secured by this part H, which I call a loopenholding the ends close to the neck of the twister and looping orcrimping them underneath itself against the cutter-plate below.

The cutter-plate I, the front edge of which should be of hardened steel,-is secured as to one end to the bracket B, and the other end is loopedaround the neck of the twister and forms a ledge, on which the ends ofthe band are crimped before being twisted, and the cutter E sheersagainst the hardened edge of this plate in severing the binding-wire.The pinion G is provided with a cam-projection or stop-plate, g, theouter or workingface of which is fitted to slide upon a circular waythat is vturned or cast upon the wheel A, thereby preventing the pinionfrom turning except at those points where said stopway` is cutaway ordepressed for the purpose of permitting said pinion to revolve. Thepinion F is provided with two similar cam-projections or stop-plates, f.The stop-plates are at the same radial distance and on opposite sides ofsaid pinion, and have their working-faces preferably parallel with eachother and fitted to slide upon another similar stopway on said wheel,thatprevents said pinion from revolving except when it is cut away ordepressed for that purpose. I use two stop-plates on this pinion, so asto be able to give the twister D, when required for the purpose ofdisposing properly the two ends of the band,l only one-half arevolution, and then holding it at rest.

In operation, one revolution of the shaft J and of the wheel A measures,as herein shown, but not necessarily, the time taken in binding abundle, and it is desired that the twister' shall have imparted to itseveral revplutions to twist the ends together, and then come to restand be held in position to receive the ends of the band when properlypresented, while the cutter requires only one revolution to cut theband, and thereafter should be at rest and held out of the way ofentanglement. The wheel A, therefore, is provided with a series ofteeth, a,meshing with the pinion F, extending a portion of the wayaround the wheel, and these teeth arc sufiicient in number to give saidpinion preferably three or four revolutions, and are arranged inconnection with the stopway 7c and the teeth and stop-plates of pinionF, so as to rotate the pinion with the twister while the band is beingsecured, and to prevent them from turning while the other operations ofbinding are being performed, or at least while the ends of the band arebeing presented to the twister. The wheel A is also provided with a setof teeth, c, which in practice are, or may be, extensions of a portionof those already mentioned, and which mesh with the teeth of pinion G.These teeth are suf-.

cient in number, and are so arranged in connection with the stopway land the teeth and stop-plate g of pinion Gr as to rotate the pinion withthe cutter one revolution to sever the band, and then hold the cutter atrest and out of the way during the rest of the process of binding. Whilethe cutter is at restitis made to hold the end of the band. The saidmovement of the cutter I have shown, and prefer to make, coincident withthe first revolution of the twister. At the conclusion of the revolutionof said pinions the plates fand g, respectively, engage with the planesurface k and Zupon wheel A, so that said pinions are restrained fromrevolution until they again engage with the teeth a and c, respectively.

There is also upon the wheel A a second set of lteeth, fm, in the lineof the teeth a, and in number sufficient to impart to the pinion Fone-half of a revolution, the purpose of thesame being to cause thetwister to engage with the wire near the end and carry it vone-half theway round the axis of the twister, so as to be out of the way of theband-wire that is brought down by the binder arm or carrier, whereby thetwo wires, when being twisted, are disposed upon opposite sides of theaXis of the twister, and in the act of twisting are carried bodilyaround each other instead of being merely twisted without passing aroundeach other, as might be the case if both were disposed upon the sameside of the axis.

In Fig. 1 the parts -are represented in the position occupied when readyto receive a bundle to be bound. The end of the'bandwirea is then, asshown, griped between the cutter E and. the plate e, and the twister hasmade its half-revolution, carrying the bandwire half-way round the axisof the twister. Ordinarily, 1 prefer to make this half-revolution of thetwister just before the other end of the band, having nearly completedthe circuit of the bundle, is presented to the twister.

In Fig. 4 the parts are shown in the position occupied when the carrieror binder arm has descended and carried the band wire round the bundle,and the twister is ready to be operated to complete the twist. Thesucceeding movement is caused by the engagement of the pinion F with theteeth a, which rotates the twister several times around its axis,thereby twisting the wire.

At or about the time the twister commences to rotate the teeth c engagewith the pinion G, causing the cutter to make one revolution, wherebythe end of the wire is released and the wire again severed, and the newend griped between the cutter E and the plate e, as before. Prior to thereleasement of the old end and lthe severing of the new end, asdescribed, the rotation of the twister D has carried each of the ends,respectively, nearly around thev neck of the twister, between it and theloop of the looper H and somewhat underneath the latter, whereby, afterbeing released and severed,'they are held in engagement with the hooksof the twister, while the subsequent revolutions of the latter twistthem together.

After the twist has been completed the bundle is liberated, and may bedischarged from the machine by any devices suitable to that purpose, asby the rotation of the arms M, that bring up another gavel to be bound.

Having described my invention, whatI claim as new 1s y l. In anautomatic binder, a rotating twister and a rotating holder and cutter,having coincident axes, combined with intermittently-rotating operatingpinions and a continuouslyrotating actuating-wheel, provided with teethand stop surfaces or plates attached thereto, whereby the various andcomplicated functions and intermittent rotations of the twister, holder,and cutter, independently and conjointly, with ,their necessarily variedperiods of rest are secured by the simple and continuous rotation of thewheel, as set forth.
